You'll need this not-yet-applied patch which adds cp15 perf reg support:
http://patchwork.ozlabs.org/patch/92423/
I've temporarily put a test kernel and initrd here:
http://people.linaro.org/~pmaydell/linaro-20110228.tar.gz
configure qemu with --target-list=arm-softmmu
and then you can run:
./arm-softmmu/qemu-system-arm -kernel
linaro-20110228/vmlinuz-2.6.37-1003-linaro-vexpress -initrd
linaro-20110228/initrd.img-2.6.37-1003-linaro-vexpress -M vexpress-a9
-cpu cortex-a9 -serial stdio -m 1024 -append 'root=/dev/mmcblk0p2 rw
mem=1024M raid=noautodetect console=ttyAMA0,38400n8 rootwait
vmalloc=256MB devtmpfs.mount=0'
At the moment this aborts when the kernel tries to initialise the
display; if you fix the problem it ought to display a penguin on
the graphics window (although it will drop you into an initramfs
prompt because you don't have a root filesystem sd card image).
